What's the Matter
These are the easiest properties of matter we can understand using our basic senses.
What are appearance (and odor)?
Pg. 55, Appearance and odor section
This is the smallest unit of a chemical substance that retains its physical and chemical properties, formed by two or more atoms bonded together.
What is a molecule?
Pg. 45, BTD
This state of matter makes it look like the particles that make it up don't move, but they do!
What is a solid?
Pg. 51, Solids section.
This describes the ability of a solid to be hammered, pressed or rolled into thin sheet without shattering.
What is Malleability?
Pg. 59, Malleability section.
Crushing a soda can or cutting up a ribbon is described as making this kind of change to the objects.
What are physical changes?
Pg. 63, Volume and Density Changes.
This is the substance in a solution in which a solute dissolves.
What is a Solvent?
Pg. 47, BTD
This is the smallest chemical unit of an element.
What is an atom?
Pg. 44, BTD
Particles in this state are in constant motion and have the most kinetic energy.
What is gas?
Pg. 52, Gases section
This physical property is unique to each substance and is the ratio of the mass of a substance to its volume.
What is density?
Pg. 56, Density section.
This is the type of change that occurs to a substance when it transitions form a solid to a liquid, or a liquid to a gas. An example would be chocolate melting.
What is a phase change?
Pg. 65, Phase change section.
This property of matter is any characteristic of a substance that can be observed of measured without changing the composition or the identity of the substance.
What is Physical property?
Pg. 55, Physical property section.
A homogenous mixture made by dissolving one substance in another.
What is a solution?
Pg. 47, BTD
This state of matter has weaker attraction between particles and do not have enough kinetic energy to free themselves from the forces of attraction.
What is a liquid?
Pg. 52, Liquids section.
While not an -ity, this physical property is used to determine the uses of substances and can be measured using the scratch test.
What is Hardness?
Pg. 59, Hardness section.
This is the type of phase change that occurs when a gas changes into a liquid.
What is condensation?
Pg. 66, figure 2.31
This is the type of mixture that when mixed together, the two parts are noticeably different from one another.
What is a heterogeneous mixture?
Pg. 46, third paragraph.
This is the energy an object has due to its motion.
What is kinetic energy?
Pg. 50, BTD
Because liquids and gases are constantly in a state of motion, this word describes how they spread out form areas of high concentration to lower concentration.
What is diffusion?
Pg. 53, BTD
What is Viscosity?
Pg. 60, Viscosity section.
This is the type of change that changes the ability of one substance to dissolve into another and is highly affected by temperature change.
What is solubility?
Pg. 67, Solubility changes
Sugar shares two of the elements that make up water. This is the third element that makes sugar in addition to the two elements that make up sugar and water.
What is carbon?
Pg. 47, Figure 2.11
In science, we describe substances based on their _______ and ________ properties.
What are physical and chemical properties?
Pg. 55, Properties of Matter
In Experiment 2.2, this liquid had the highest density which only allowed the heaviest objects placed in it to become submerged.
What is corn syrup?
Pg. 57, Experiment 2.2
This chemical property describes a matter's ability to combine chemically with other substances to form new substances.
What is reactivity?
Pg. 62, Reactivity section.
This artist wrote the song 'Changes' and like the parable of Lazarus and the rich man, says not to be this.
Who is David Bowie, and not to be the rich(er) man.
"Changes",lyrics.
Ch-ch-ch-ch-changes (Turn and face the strange)
Ch-ch-changes, don't want to be a richer man
Ch-ch-ch-ch-changes (Turn and face the strange)
Ch-ch-changes, just gonna have to be a different man
Time may change me
But I can't trace time
